What else can I help you with?
In a plasma membrane how do the tails of the phospholipid molecules lineup?
they are sandwiched between two layers of heads
What are the specialized parts of the phospholipid bilayer?
The Phospholipid Bilayer is made up of phospholipids. These phospholipids have a hydrophillic head, and a hydrophobic tail. They are structured so that the hydrophillic head interacts with water, and the hydrophobic tails stays away from water, but mixes with fat. This makes the phospholipids form the phospholipid bilayer. The Phospholipid Bilayer has intrinsic proteins and extrinsic proteins attached, which may have glycoproteins attached to them. Glycolipids may also be attached to the hydrophillic heads of the phospholipid. Cholestrol is also part of the phospholipid bilayer, which adds strengh to the structure.
Does the cell membrane include a triple layer of phosphlipids?
The cell membrane is made up of two layers of molecules, so it's called "bilayer" ("bi" means two). The molecules in this bilayer are called phospholipids. Here is what they look like:Type your answer here...
Why is the phospholipid molecule so appropriate as the primary structural component of plasma membranes?
Phospholipids have a hydrophilic head and hydrophobic tails, allowing them to form a bilayer structure with the hydrophobic tails pointing inwards and the hydrophilic heads facing outwards towards the aqueous environments, creating a barrier that separates the internal and external environments of the cell. This structure is crucial for maintaining cell integrity and regulating the movement of molecules in and out of the cell.
Where is cholesterol found in cell membrane?
The plasma membrane is present in all prokaryotic and eukaryotic cells. It is the semi-permeable membrane that encloses the cell. So to clearly answer your question, the plasma membrane is found on the outside of the cell; it encircles the cell.

Which part of a cell controls what gets in and out?
The plasma membrane / cell surface membrane. The phospholipid bilayer prevents certain substances passing straight through, so protein channels and other mechanisms control what does and does not pass in and out of the cell.
What do cell walls do in plant cells?
They keep the structure so that the contents of the cell do not spill out.

Why is a cell so important?
A cell is important because you could not live without them.

What part of a phospholipid is polar and non-polar?
The phospholipid bilayer in cell membranes is both polar and nonpolar. The heads, which face the outside and inside of the cell, are polar. Thus they form hydrogen bonds with the water outside of the cell and the cytoplasm inside the cell. They are called "hydrophilic," which means they love water. The tails are on the inside of the bilayer and are nonpolar. They are hydrophobic, which literally means they are scared of water.
What organelles should not be in your animal cell?
The definition of organelles is that they are inside the cell; inside the cell membrane (phospholipid bilayer). So anything that is inside the cell, other than the organelles, are treated as invaders, and the lysosomes will attack and digest them. This is a part of the body's immune response
Why would fat substances rapidly affect a cell?
The cell membrane is also called a phospholipid bi-layer. In other words, it is like an Oreo cookie, with a layer of lipids on both sides, made of fat, with a layer of phosphorus in the middle. So every cell in your body needs fats in order to form and function properly.
Why are chloroplasts so important in a plant cell?
so that the cell can get the food and nutrients it needs
